Be it known that l, Cnlnis'rien C. ST L- znneuno, a citizen of the United States,residing at lilyria, in the county of, Lorain and. State of Qhio, have invented certain new and usefulImprovementsin Cushionliieels, of which the following is a specification. 1 r J This invention relates to improvements in cushion heels, and it is the principalobject of the invention to provide a novel form of anti-slipping tread for, "ubber or cushion heels, said tread being ofa unique design andserving to prevent the slipping of a person using the same by reason of the firm and positive gripaii'orded by the cooperat mg portions thereof.

Another and equally important object of the invention is to provide a heel formed with means for producing air cushions when attached to a shoe and in use, thus, adding to the qualities of the same.

Other objects will be in part obvious and.

in part pointed out hereinafter.

lhe improvements in the details and arrangement of parts will be apparent from an inspection of the accompanying drawings, in connection with the specific description hereinaftercontained and wherein the preferred embodiment of the invention is disclosed for the purpose of imparting a full understanding thereof.

In the drawings:

Figure 1 is a bottom plan view of the improved heel showing the novel form of tread,

Fig. 52 is an edge view thereof,

Fig. 3 is a top plan view of the heel, showing the form of air cushioning means einployed,

Fi l is a vertical transverse section through the heel, and

5 is an end elevation of the same.

Having more particular reference to the drawings, in connection with wh ch like reference characters will designate corresponding parts throughout the several views, 1 represents the improved cushion heel in its entirety, the same being formed of rubber or some similar material, such as conditions or preference may dictate, having a recess 2 formed in the face or tread portion thereof, preferably,- approximately centrally thereof and in form of a bell, the constructed or reduced end of the bell-shaped recess be- Spebi'ficaticn of Letters Patent.

ing disposed toward the rear end ofthe heel as indicated at 3 and terminating in a small extension forming a vacuum breaking pocket, while the enlarged or flared end of said recessis disposed toward the forward portion of the heel 15 indicated at l. this connection it may be set out that the forward'portions of the sides of the bellshaped recess are curved as ate, and as will be readily understood, lend to the efiiciency ofthe heel byproviding gripping surfaces other than the longitudinally and; transversely disposed gripping surfaces and,

hence, lessens liability oftheslipping of the.

person using thesamepwhile a strip 2. is arranged, across the enlarged portion of the bell and "has its tread portion extended beyondthe heel tread and the tread portions of the anti-slipping means, hereinafter described, whereby to cause the weight ofa wearer to be directed thereonto, thus disturbin g the recess 2 and in consequence serv- In I ing to prevent the retention of dirt and the i.

nectionand to prevent the heads of the se curing devices from leaving the body of the cushion heel. it may be here noted that the various bell-shaped proyections 6 are arranged in disalined relation and are so disposed as to increase the anti-slipping efficiency of the heel tread so formed; the irregular outline of the projections, obviously,.serving to provide a desirable and effective surface engaging means.

Formed on the upper side or face of the heel l. is a bell-shaped recess or pocket 9 arranged so as to form an air cushion when the heel isattached to theheelportion of a shoe by the fastening devices passed through the openings 7, hence, lendlng materially to the cushioning or resilient qualities of the heel. To brace that portion of the heel'having the recess 9 therein whereby toprevent collapsing of the same under weight, a strip 9 is molded integral with the heel and eX- tends longitudinallythrough said recessand has an enlargement or head 9 formed on its free end,which as will be understood, en-

gages with a portion of the heel portion of I i I said recess extending beyond the surface of the lower face for engaging the groundto prevent slipping and to prevent accumulaa shoe. 7 s a a Attention is directed to the factthat the face'of a heel having theair. pockets 9 formed therein is dished as at 10, thus, facilitating functioning of the air" pockets when arranged adjacent the heel portionof a shoe and also insuring proper engagement of the outer portion of a heel with the heel portion of a shoe to prevent the escape of air from the pockets.

From'the foregoing, it will beappreciated by persons skilled in the art that have provided an exceedingly simple and effectual form ofcushlon heel and anti-shppmg tread therefor; the tread by reason of 1ts design rendering the heel on which it is formed -novel, aswell as practical.

Manifest'ly, the construction shown modification as is within the scope 'ofmy claim, I consider within the spirit of my invention.

I claim: A rubber heel comprising upper and lower faces, the lower face having a bell-shaped recess formed therein, a transverse rib across tion of mud in the recess, the upper face having a bell-shaped recess formed therein,

longitudinal rib in the recess and terminating short ofone end and above the central portion of the transverse rib' on the lower face for cooperating with the transverse rib in reinforcing the material between-the recesses, an enlargement or head on the terminal end of the longitudinal rib above the central portion of the transverse 'rib for forcing the central portion of the transverse rib downwardly into the engagement with the ground upon application of weight or pressure upon the heel.

, is ca .pable of considerable modification and such CHRISTIAN C. STOLZENBURG.
